ABS light comes on,4X4 light flashes,on accelaration vehicle locks up

[park7163@sympati]

I have a 2006 Explorer equipped with advance trac and 4 Liter . I was driving home when suddenly the ABS light flashed on. I got home but the 4X4 light flashed on. The strange thing now is I can put the truck in gear but when I press the gas pedal it locks up but as soon as I let up on the accelerator it will coast but again it locks as soon as I accelerate

Check the front 2 hub assemblies and connectors, and rear hub rings for cracks.
